摘要： A nuclear reactor fuel assembly includes mutually parallel fuel rods and guide tubes for control rods. Two lattice-like spacers have mesh openings formed therein. One of the fuel rods or one of the guide tubes is guided and secured in each of the mesh openings. An additional lattice is secured at least to one of the guide tubes between the two spacers as seen in the longitudinal direction of the fuel rods and the guide tubes. The additional lattice has mesh openings formed therein defining sides of the mesh openings and a smooth and flat surface of the additional lattice in the mesh openings. Turbulence-promoting vanes protrude beyond the sides of the mesh openings formed in the additional lattice. One of the fuel rods is guided with play or one of the guide tubes is guided through each of the mesh openings formed in the additional lattice. Brackets grip the additional lattice between at least one of the fuel rods or the guide tubes at the outside of the fuel assembly.

摘要： In a fuel assembly, rods are disposed in meshes of a grid. Crossing points of the grid are distributed in a checker-board-like manner, partly in an upstream crossing plane and partly in a downstream crossing plane. Webs of the grid run in zigzag form between the two planes. As a result, flow resistance which is produced by the webs and/or by mixing vanes disposed thereon and by flow turbulences is shifted into different axial planes and is considerably reduced.
